It would be cool to have a bigger version of embrace shadows for higher level agents. Not to replace what embrace shadows does, but instead provide invisibility that burns focus over time sorta like meditations or that distraction dance thing that performers can do. The amount of focus burnt could depend on how many people/npcs are in the area, time of day, in combat or not, etc._________________A bright-eyed Thekko Ku Kalla dressed in a dapper sailor suit takes to flight and careers through the air toward the Modan Kucho and slams into him!

+ for anything that makes agents use focus. Right now it's a dead trait to us. Also + for this idea._________________>ask librarian about books
